ISO 3871:2000

Overview

ISO 3871:2000 is an International Standard developed by ISO that specifies the minimum labelling requirements for commercial containers of brake fluids used in road vehicles, including mopeds and motorcycles. This standard covers both petroleum-based and non-petroleum-based brake fluids, which are essential for braking and hydraulic systems. The labelling guidelines ensure clear communication of safety information and product identification, supporting safety, regulatory compliance, and proper vehicle maintenance.

Key Topics

• Labelling Requirements
  Containers must be clearly labelled with the type of brake fluid inside, using designations in capital letters such as:

  • BRAKE FLUID, PETROLEUM-BASED ISO 7308
  • BRAKE FLUID, NON-PETROLEUM-BASED ISO 4925

• Label Placement and Visibility
  The labelling, including all required information, must appear prominently on the main panel of the container. Letter height must be at least 3.2 mm, printed legibly in a contrasting color for high visibility and durability.

• Identification and Traceability
  Each container is required to include a serial number detailing the pack date and lot number. Additionally, the packer’s name or code and the distributor’s full postal address must be visible to ensure traceability.

• Brake Fluid Type Symbols
  For petroleum-based fluids, corresponding graphical symbols as per ISO 9128 must be displayed for fast recognition of the brake fluid type.

• Minimum Wet Boiling Point
  Containers of non-petroleum-based brake fluids should list the minimum wet boiling point (in degrees Celsius), measured according to ISO 4925, important for performance and safety validation.

• Safety Warnings
  Mandatory safety statements on the container include:

  • Following the vehicle manufacturer’s brake fluid recommendations.
  • Keeping brake fluid clean to prevent contamination that may cause brake failure or damage.
  • Storing brake fluid only in its original container, keeping it tightly closed and uncontaminated.
  • A specific compatibility warning for petroleum-based fluids highlighting incompatibility with rubber components designed for non-petroleum brake fluid systems.

• Additional Safety Information
  If necessary, further details such as toxicity or flammability warnings may be added to enhance user safety.

Applications

ISO 3871:2000 is crucial for manufacturers, distributors, and users of brake fluids in the automotive sector, particularly:

• Brake Fluid Producers need to comply with labelling to meet international market regulations.
• Automotive Workshops and Mechanics rely on proper labelling to select compatible brake fluids for servicing various vehicle types.
• Consumers and Vehicle Owners benefit from safety and product use information to avoid misuse and ensure brake system reliability.
• Regulatory Authorities use this standard to enforce consistent packaging and labelling practices to enhance road safety and environmental protection.

The standard applies to a broad range of road vehicles, including motorcycles and mopeds, reinforcing universal safety standards across vehicle categories.

Related Standards

• ISO 4925:1978 – Specifies requirements and classification for non-petroleum-based brake fluids, referenced for testing and boiling point determination.
• ISO 9128:1987 – Defines graphical symbols used to designate brake fluid types on containers for easy identification.
• ISO 7308:1987 – Details petroleum-based brake fluids used in stored-energy hydraulic brake systems, referenced for proper labelling of petroleum-based products.

Compliance with ISO 3871 complements these related standards, creating a robust framework for brake fluid safety, identification, and standardization in the automotive industry.

By adhering to ISO 3871:2000 labelling requirements, manufacturers and distributors ensure that petroleum-based and non-petroleum-based brake fluids are correctly identified and safely handled, enhancing vehicle safety and maintenance operations worldwide.
